Measuring Big Bird

Nina is using a smiley face growth chart to measure how tall Elmo and Rosita are. Big Bird wants to see how tall he is too, but Nina is all out of smiley faces. What else can they use to measure their tall friend? After trying a few ideas, inspiration strikes. What if they make their own smiley faces? It works! Because they didn’t give up, all the friends—including Big Bird—could be measured.
